Investigation of explicit finite-element time-domain methods and modeling of dispersive media and 3D high-speed circuits
… are recovered. This method maintains the unconditional stability of the finite element time-domain (FETD) method and generates results that are identical to FETD. Moreover, the algorithm is highly parallelizable since the computational time is dominated by the solution of subdomain …

High Order Energy - Conserved Splitting FDTD Methods for Maxwell's Equations
… scheme is proved to be energy-conserved, unconditionally stable and of fourth order convergence in space. Secondly, we develop and analyze a new time fourth order EC-S-FDTD scheme. At each stage, we construct a time fourth-order scheme for each-stage splitting equations by converting the …

Efficient high-order integral equation methods for the heat equation
… of the problem by one, high order accuracy, unconditional stability, insensitivity to different geometries, and elimination of truncating the computational domain and the need of artificial boundary conditions for exterior problems. However, the heat layer potentials contains convolution …

Efficient High Order Ensemble for Fluid Flow
… are demonstrated to be second-order accurate and unconditionally stable with respect to the system energy through comprehensive stability analyses and error tests. Two algorithms make use of Artificial Compressibility (AC) to update pressure and a solenoidal constraint for the magnetic field. …

NEW COMPUTATIONAL METHODS FOR OPTIMAL CONTROL OF PARTIAL DIFFERENTIAL EQUATIONS
… problems. The new leapfrog scheme is shown to be unconditionally stable and it provides a second-order accuracy, while the classical leapfrog scheme usually is well-known to be unstable. A mathematical proof for the convergence of the proposed scheme is provided under a suitable norm. Moreover, …
